This all-carbon-fiber laptop—a first in the genre—is only an inch thick and weighs in at just under three pounds. Even better, beneath its light frame lurks a battery that's good for more than four hours worth of power-hogging DVD playback. There's also a built-in webcam, fingerprint reader, and an instant mode that lets you play media without fully cranking up Windows Vista. As an added bonus, the sleek design almost makes you look forward to airport security lines. Well, almost.
